`To @ZZ whom it may concern.:

ABe it known that i, HOWARD M. DUDLEY, aV citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Apparatus Yfor Dyeing or @ther-y wise Treating Fibrous Material, of which the following is a specification. Y

My invention relates to apparatus employed 'for dyeing goods or material in the mass; t-hat is to say, finished goods such as hosiery or the like, which may be loosely disposed in a drinn containing the dyeing or.

treating liquid. Apparatus of this type is particularly applicable 'for dyeing hosiery in bulk, although available for dyeing or otherwise treating other forms of material under similar conditions. n

@ne important object of my present invention is to provide an imperi'orate, rotating drum, the interior ot which comprises a continuous chamber, 'with oraminous .compartments or hollow partitions ext-ending longitudinally et' and projecting a short distance into the space of said chamber radially; certain ot said compartments lying adjacent to the outer imper'torate wall oi the drum casing, while other compartments lic adjacent to a central-shell or partition.

A iurther object ot my invention is to :provide means tor circulating the dyeing or treating liquid in two directions through the interior oif the chamber provided by the otatable drum.

A further object oit my invention is to provide means lor introducing steam into the chamber ot' the drum, and a still further object of my invention is to provide means whereby the drum and its contents may be rotated while the means through which the dyeing or treating liquid is introduced andv discharged and the means employed igor introducing a heating medium such as steam or any other fluid, remain at rest.

These and other features oit my invent-ion are more iiully described hereinafter; reiference being had to the accompanying drawings, in which:

Figure l. is a longitudinal elevation of one torm ot apparatus within the scope o'i' my present invention, in section on the line iwi, Fig.

'Figs 1.3and 14:,V are sectional views en the lines XIII-XIII, and XXV-Klv, Fig. 12,. looking in the direction i et' the arrows a' and y, respectively.

The rotatable drum torn'iing the subject ot my present invention may be'madc up ot', an end wall 1, an annular wall 2, and an end wall 3; the .latter carrying a plurality ot- .hollow, toraminous compartments or hollow said wall 3, for the passage ot dyeing or treating liquid to vand 'trom the drum, asV more fully described hereinafter. r)Che solid portions ot the end wall 3, together with the end wall 1, and the annular wall 2, form an internal chamber 5, tor the reception oi' the material to be treated, through which chamber the treating or dyeing liquid may be circulated via the foraminous compartments ft' and It, and the tubular channels G and Ga.

rihe annular wall 2 o't the drumfmay be provided with a door i', closinga discharge outlet 8, and such door may be connected to. the wall 2, by hinges 9. This Idoor ma;r have its marginal edgesgrooved at 10, for the reception ot a gasket 101i, tor .Contact with the outer surface et the annular wall of the drum, and clamping means maybeV provided whereby said door is held in liquid-y tight engagement with said annular wall. Said clamping means may comprise L- shaped members 11, adapted to overlie the door and lit over bolts 12, carried by the annular Wall 2; being held down by nuts 121, provided with suitable operating handles. It desired, this door 7 may carry a supplemental door 7a, held thereto inliquid-ti-ght engagement in the same manner that. the door 7 is held to the annular ivall ot the drinn; such door 7a being hinged to the door 7 at 9a,'and closing an opening 8a, through Which samples oit the material under treatment may be removed Jfrom time to `time to observe the action ot the dyeing or treating liquid thereon.

As indicated above, the interior of the drinn is continuousso that the material under treatment is free to move throughout the same; being tumbled about in contact with the dyeing or treating` liquid as the drum rotates. benelicially aii'ect the material during a dyeing or treating operation, l' extend into the drum from `the Wall 3, and in the present instance constituting a part otsaid Wall 3, a

series of 'foraminous compartments, hollowpartitions or liquid conveyingchannels 4 and 4; those indicated atv 4 lyingyadjacent to and being supported by the annular VWall 3, While those indicated at 4a lie adjacent to and may be supported by the ivallso'f a central core or partition 18, as clearly shovvn in the drawings, On the opposite Aside of said Wall 3,'the series ot hollow channels-*Gand G are provided, through-Which thedyeing or treating liquid-maybe passed from a suitable source to and from-the drinn `chamber 5; the channels G communicating ivith the compartments or holloiv partitions 4, and the channels 6 communicating With the compartments or holloiv partitions 4, respectively.

r1`he toraminouscompartments or liquid conveying channels 4, lyingadjacent to the annular Wall 2, may have a cross sectional contour such as illustrated in Figs. 5, 6 and 7,'and the interior of the same may be divided into a plu ality ot chambers, two -in the present instance, indicated at 14 and 15, separated by a oraminous Wall 16. The Wall of the chamber 14 may be rounded as indicated and perforated or otherwise apertured as indicated at 17, and this chamber' serves as a portion of the liquid conduit; that is to say, the liquid may enter the drum chamber through the apertures 17 leading from the chamber 14 of the compartments 4, or it may be discharged from the drinn chamber through these apertures.-

The foraminous compartments 4or liquids conveying channels 4at lying adjacent tothe walls of the central core or partition 13, have a cross sectional contour substantially like that of the compartments 4, and the inte- In order that this action may rior of the same may be divided into a plurality-ot chambers, twoin the present instance, indicated at 14a and 15a, separated by a foraminousl Wall 16a. The Wall o1 the chamber 14a4 may be rounded vas indicated, and perforated-or otherwisel apertured as indicated at 17, and serves as a portion ot the liquid conduit, that is to say, the liquid may enter the drum chamber 5 through the apertures 17a leading from the chamber 14a oit the compartment 4a, or it may be discharged trom the drum chamber through these apertures.

The chambers 15 and 15Ll contain pipes 18 and 18, a portion of the Wall of which is perforated at 19 and 19l adjacent the foraininous partition Walls 16 and 16a, so that steam or other tluid passed into said pipes 18 and 18a from a suitable sourcemay be discharged theretfrom through the apertures 19 and 19, thence through the foraminous Walls 16 .and 16a, into the chambers 14 and 14a, and out through the apertures 17 and 17a of the latter, togethe With-the treating or dyeingliquid,into the drum chamber 5. The VYtoraminous compartments or hollow partitions 4 and 4a maybe flanged as indicated at 2O and 203-; the lianges20 lying adjacent the outer Wall to the drum, While the -flanges v2011.01?` the compartments 4a serve as supports for the Wall of the central core or partition 13.

The channels 6 and 6 carried by the Wall 3 lniayexteiid diagonally toward a shelllilre structure comprising a pair of chambers concentrically disposed; the channels G commuf nicating with an outer chamber indicated at 25, while the channels (3a communicate with an Iinner chamber indicated-at 26. The walls of these chambers may be` hell-mouthed as indicated .at 25and 2G to receive the projecting ends of a hollow liquid-conveying structure which may have an outer `ivall 28 -and an inner wall 29 concentric with said outer Wall; the bell-mouth 25a ot the outer chamber 25 additionally receiving packing material 30, which may be held in place by a gland 31, suitably arranged io tal-:e`

up such packingand insurea liquid-tight joint between said bellmouthand the Wall 28.` The inner Wall 29 may lit Within the bell-mouth of the inner chamber 26, the meeting faces of the Walls of the respective members being such as to pern'iit rotation of one With respect'to the other. Although the annular walls 28 and 29 -are shown as fitting Within the bell-inouths 25a and 2G, it Will be understood that the relation of parts may be reversed Without departing from iny invention. The arrangement indicated is more convenient. To insure a liquid seal between the contacting. surfaces ot the bell-mouth 2(`L and the Wall 29,y these surfaces may be annularly grooved as indicated at 33 and respectively; such grooves preferably registering and being adapted to receive any liquid which may seep between the surfaces, and such liquid collecting in such registering grooves will prevent passage ot the flowing liquid past the joint so formed.

The annular chambers formed by the walls 28 and 29 are merged into upper and lower passages 28 and 29, each having a cross partition 28b and 29?; which passages may be placed alternately in communication with passages and 36; the latter having a cross partition 36, communicating with both sides of a suitable pumping structure indicated at 37, which may be driven by any suitable means; a pulley 38, being'shovvn, receiving a belt 39 actuated by a suit-able prime mover (not shown). A pipe for delivering dyeing or treating liquid, or Water to the pump is shown at 40, and a tank 41 for containing any treating material may communicate with a conduit 36 between the passage 36 and the pump via a valved outlet 42.

The relation of the passages 28, 29 and 35 and 36 may be controlled by a gate valve 45 having a stem 46, passing through a suitably packed gland 47, and connected to an operating lever or handle 48 so that the liquid can be directed as desired; that is to say, such liquid can be delivered from the passage 35, to the passage 28, thence to the chamber 26 and channels 6, and discharged lirom the foraminous compartments 4 into the drinn chamber 5, and returned through the iforaminous compartments 4 and channels 6 to the cli-amber 25, passage 29 and `passage 36 to the pump, as indicated in Fig. 1, or discharged through the oraminous compartments 4 and return through the oraminous coii'ipartment 4 and the respective passages, without changing the direction ot the movement ot the pump. Provision is made ttor introducing any desired chemical iut-o the dyeing or treating liquid; the tank or receptacle loi such purpose being indicated at 41, and the pipe 40 supplying dyeing or treating liquid oi' water may be provided with a valve 402 l At the opposite end of the drinn, the end i plate l may be provided with a tniclrened hub 49 receiving a steam or fluid convey-V ing pipe 5l) with a suitable packed joint; a `gland 51 being provided for the purpose, and such end Wall may be bored to provide a series oli channels 52 and 53 for the passage o'lA steam or other fluid. The inner ends ot these channels communicate with the pipes 1 8 and 18 disposed within the chainbers 15 and 15L ot the-respective toraininous compartment elements 4 and 4, such pipes having a portion of their walls perforated throughout their length so that the steam or other fluid may be discharged therefrom and lFind `its way tl'irougli the oraininous partitions 16 and 16 into the chambers 14 and 14 ol' said ioraininous compartn'ients to heat or otherwise atleetk the body of dyeing or treating liquid passing through the same, as hereinbefore described.

The hub member 49 may carry a cone 55, between Which and a second cone 56, carried by a support 57, anti-friction balls, 58 may be placed, to provide a suitable bearing. The shell at the opposite end of the drum providing the chambers 25 and'26, may also be provided with a cone 55, be tween which and an outer cone 56, carried by a support 57, anti-friction balls 58 may be disposed.

By providing the angularly disposed channels 6 or the shell forming the chambers 25 and 26 with a suitable pulley face, such as indicated at 66, in Fig. 1, the drum may be rotated by means of suitable belt from a driven element, or, in lieu ot the pulley Jace, such shell may carry a gear wheel 61, to be positively driven by a motor driven pinion, or :from any other suitable form ot prime mover, as shown in Fig. 2.

rlhe drinn may be provided with a drain valve 62, disposed near the marginal wall thereof, and the end wall 1, may carry one, or a series ot liquid gage glasses 6,3, in order that the height of the dyeing or treating liquid in the drum may be ascertained at any time.

llVhile I have shown in Figs. 1, 2, 3, et

seq., oraininous compartments or hollowV partitions 4 and 4, disposed Within the drum vchamber and comprising apertured shells carried by or attached to the end plate 3 and extending longitudinally of the drinn chamber, it is possible to ii'iodiy-such construction without departing from my invention, and to employ a construction such as illustrated in Figs. S), and 10,-V in which a channel member A may be provided and arranged to receive a pipe 18b apertured for the discharge or' steai'ii or other tluid, .and in lieuo'li a chamber 14 or 14., liaving an apertured wall through which the dyeing or treating liquid passes, this wall may be made up oit a series ot longitudinal rods or bars 66 forming a slatted construction through which the liquid may be discharged into the drum chamber or from which it may be withdrawn, depending upon the direction oit movement ol' the same.

While l have shown and described an end plate 3 as carrying the toraininous compartments 4 and 4 on one side, and the channels 6 and 6, on the opposite side, andas integral parts ol said plate 3, it will be nnderstood, o't course, that these several members may be separately constructed .and properly secured to said end plate 3 in order that the proper conduits or passages for the liquid will be provided so that such vliquid may pass into two directions to and from the' drum chamber 5, without departing from my invention. It' desired, the endwall construe-V tion may include a casing in the form of a truncated cone, as indicated by dotted lines` Figs. l and 2, and this casing may be integral with or independent ot the several channels, as may be convenient or desirable.

lVhile I hare described my improved apparatus as being'speciallj/ designed for dyeing, preferably ttor dyeing material in bulk, it 'fill be understood that it may be employed ior various niaterials and for the purpose ot scouring and bleaching, and that in lieu ot introducing' dye liquor into the drum chamber receiving' the material operated upon, l may introduce gaseousl'iodies,

bleaching' tiuids, scouring liquids or the like, y

without departing' 'from my inif'ention.
